Effects of Configuration Interaction on Dielectronic Recombination of Cu-Like Gold Ion through 3d+ e →4l'l'' Capture Process

Effects of configuration interaction on dielectronic recombination of Cu-like gold ions through the 3d+e → 4l'4l'' capture process are studied in the models of isolated configurations approximation, configuration mixing within 3d⁹4s4l'4l'', and configuration mixing within 3d⁹4l4l'4l'' (l≥0), employing a relativistic distorted-wave approximation. Nonresonant raditive stabilizing transitions and decays to autoionizing levels followed by radiative cascades, as well as resonant stabilizing transitions from the resonant levels, are taken into account. The additional mixing with 3d⁹4l4l'4l'' (0
